6 Claims. (crass-e This invention relates to improvements in' spraying devices for hot rod mill reels;

In the manufacture of wire rods,suitably heated billets are continuously reduced, by being 5.139.8586. through a'series of roll stands and are reeled, while still in a highly heated condition. Reelsused'for thispurpose rotate at a relatively .high rate of speed, and are known in the art as pouring reels. It has beenfound that'if the hot rods'were'sprayed with water, or other'suitable liquid, a great deal of the scale on the'hot rods would be loosened, which would facilitate its complete removal by acid pickling in a subsequent operation. One object of the present invention is to provide a novel liquid spraying device for spraying rods while they are being poured on a conventionalhot rod mill reel, the spray originating fromthe centerof the coil so that centrifugal? V force will throw the water into and through the coil, and'steam being generated which envelops the coil during cooling. v

Another object of the invention is to provide 'a' novel spraying device for hot rod mill'reels which can be easily and quickly placed into and out of operativerelationship with respect to the reel, in. such manner as not tointerfereiwith the strippingof the coiled rod from the reel.

'These and further objects will appear referring to the drawings, "in which:' v Figure 1 is a sideelevation of the apparatus of the invention as associated with a conventional hot rod mill reel, which is shown insection.

Figure 2 is an end elevation of the apparatus, showing the hot rod mill reel and part of its associatedfpusher mechanism in section.

Referring more particularly to the drawings, the numeral 2 designates a conventional hot rod -mill reel tub. A conventional pouring? reel is 40 disposed in the reel tub 2, and comprises a rotary.

base 3, which is provided with a centrally disposed hydraulically-actuated vertically movable shaft 4 A disk 5 is journaledon the upper end of the vertically movable shaft 4 and is provided with a number of suitable apertures to receive the guides 6 which are mounted on the rotating base 3 of the reel. Rotation of thebase 3 will, of course, rotate the guides 6 and the disk 5. A suitable tube from the last'roll pass of the rod mill will direct the hot rod to a suitable aperture in the tub 2 and thence to the reel.

A support '7 is disposed adjacent the upper portion of the reel tub 2, and is provided with a shaft 8 journaled therein, the latterbeing associated with a hydraulic cylinder (not shown). A horiafter is secured to'the pipe14.

zontal supporting arm, generally indicated at 9,-

is secured to theupper end of the shaft 8 and is-providedwith a cover 10v for closing the top of the reel tub 2. A vertically disposed plate 12 is secured to the horizontal supporting arm 9'in any suitable manner, and, is provided with journals 13 and 13 at its upper and lower ends, re-, spectively. A pipe 14 is'dispo'sed in the journals. 13 and 13 and adaptedfor movement relative to the vertically disposed plate 12.

The pipe 14 carries a spray-head 15 atits lower end, and a connection 16 at its upper endwhicli' is connected with a supply hose. 17. The supply hose 1'] is connected at its other end'to a suitablejoint 18 mounted on the upper end of the shaft 8., A sleeve 19 is connected to the connection 18 at one of its ends and to a liquid supply'hose 20 at its other end. A suitable liquid supplying convduit 21 and valve 22 supply the hose 20. A valve 23 is positioned between the sleeve 19 and connection 18, and is provided with an operating arm 24. The upper end of the shaft 8 is provided. with a pivot 25, on which there is mounted, in an offset manner, a lever 26. The lever 26 carries a link 27 adjacent one of its ends for actuating the '80 operating arm 24 for the valve 23, and also a linkv 28 which is connected to a weight 29. The weight 29 rests on'a suitably disposed platformi30. A safety trip 31 is mounted on the platform 30 for operative .association'with a safety trip lever 32,35 which is carried on the lever 26 adjacent the pivot 25. 'A link 33 is connected to the other end of the lever 26 and at its other end to a collar 33 which A trip trigger 34 is pivotedto the support 7 and providedat one of its ends with a treadle 35, and at the other of its endsjwit-h a latch 36, the latter being adapted to seatin a cooperating recess, 3''! in the shaft 8. j l In operation, while the hot rod is being delivered and coiled on the disk 5 of the pouring? reel, the horizontal supporting arm 9 of the spray ing device will be in its lowermost position, the shield 10 resting on the uppermost edge of the reel tub 2 and the spray-head 15, on the pipe 14, in its lowermost position. i Water or othersuitable liquid'is deliveredby the supply pipe 21 through the valve 22, hose 20, valve '23, hose 1'7 and pipe 14 to the spray-head In practice, spraying continues for a short period of time after the rod, which is shown at A, is completely coiled, in order to give the spraying liquid sufficient opportunity to reach the outer convolutions of the coil. After the rod has been completely sprayed, the treadle 35 is depressed, removing the latch 36 from the recess 37 which permits a hydraulic cylinder (not shown) to raise the shaft 8 and its attached horizontal supporting arm 9 upwardly, the tub cover 10 moving withthe horizontal support.

The counterweight 29, which is connected to one end of the lever 26, will act to rapidly elevate the pipe 14 through the link 33 and the collar 33 which is secured to the pipe. This rapid elevation of the pipe 14 and its attached spray-head 15 is greater than the rate of elevation of the horizontal supporting arm 9 and the cover 10, and will cause the spray-head to move to a position adjacent the bottom of the cover. While the pipe is is being elevated, the lever 26 will act to draw the link 27 downwardly, and also the operating arm 24 for the valve 23 to whichit is connected, and cut off the liquid supply.

A coil pusher 40 is mounted on a shaft ll which is associated with a hydraulic cylinder 42.

.A lever 43 is pivoted on the cylinder 42, and carries a catch l3 for restraining the coil pusher 40 and an. extension 243 for tripping the catch. The catch 43 is released during the upward movement of the tub cover 10 by the contact of the extension 43' with a trip 10 which is mounted on the cover.

When the disk 5 has been elevated to a position flush with the top of the tub 2 the pusher 40 is actuated and the coiled rod A is removed.

After the coil pusher has been retracted to inoperative position the hydraulically elevated shaft 4 is lowered, carrying with it the disk .5. The horizontal supporting-arm 9 is also lowered, together with the tub cover 10, pipe 14 and spray- :head 15, and the latch 36 seated in the recess 3'7 in the shaft 8. The coil pusher 40 will be held in operative position by the catch 43 during the next reeling and spraying operation.

It is to be understood that the reel and its associated pusher mechanism are conventional, and as such form no part of the present invention other than in combination.

While we have shown and described one spe cific embodiment of our invention, it will be understood that we do not wish tobe limited exactly theretdsince various modifications may be made without departing from the scope of our inven-'.
